To LZZ whom it may concern.'

Beit known that LED'WARD L. SHORE, a citizen of the United States,residing at Eldon, in the county of Wapello vand State of Iowa, haveinvented a new and useful Reversing- Gear, of which the following is aspecification.

Myinvention relates to reversing-gear, and

- has for its object to produce a mechanism of this character in whichthe direction of rotation of a driven shaft may be instantaneouslychanged by means of improved mechanism mounted upon a drive-shaftsituated at right angles to the driven shaft.

The invention comprises the details of construction and combination ofparts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional elevation of my improved mechanism. Fig. 2 is a verticalvtransverse section on the line 2 2 of Fig. 1. Fig. 3 is a perspectiveview of the clutch member removed.

Referring to the drawings, 1 indicates a d rive-shaft operated from anysuitable source of power and having mounted idly thereon bevel-gears 2and 3, having fixed collars 4 mounted upon the shaft at their outerfaces, these collars being held in place in any suitable manner, such asby screws or the like. Thegears2 and 3 each has formed in its inner facea beveled recess 5, formed by coring out the metal of the gear or inother suitable manner.

6 is the driven shaft, having keyed thereon a bevel-gear 7, which is inmesh with the gears 2 and 3 on the drive-shaft and adapted to receivemotion from either of them in the manner and for the purpose to bepresently explained.

8 indicates a clutch member mounted on the shaft l between vthe idlegears 2 and 3. This member is xed to the shaft for rotation by asuitable spline or feather 9, but is adapted for movement longitudinallyof the shaft in order that it may engage either of the gears 2 or 3.This friction member comprises a body portion 10, having a transverseperipheral groove 11 formed therein and adapted to receive a removablecollar 12, formed in two sections, secured together by suitable vboltsor the like. The collar has formed on its edges at points diametrcallyopposite two integral lugs 13, adapted to be engaged by orifices in thelower bifurcated end of a lever 14. This lever is pivoted, as at 15, andis provided at its upper end with a spring-pawl adapted to engage teethin a rack 16 for holding the clutch member in any desired position. Theclutch member is further provided with two enlarged heads 17 and 18,beveled to conform to the beveled recess 5, formed in the faces of thegears 2 and 3 and into which they project. These heads are constructedby forming on the body of the clutch member fixed fiangcs 19, projectingat right angles thereto, and a reduced core 20, which extends outwardtherefrom. Upon the core 20 is mounted the friction material-such asleather, rubber, or the like-the outer ends of the core having appliedthereto removable disks 21, which serve to hold the friction material inplace and protect its outer face. These disks are secured to the flanges19 by means of screws or the like, which also pass through the frictionmaterial.

In operation power being applied to the drive-shaft 1 it will rotate inone direction, carrying with it the clutch member 8, the gears 2 and 3remaining idle. New if the leverbe moved to the right it will force thehead 17 of the friction member into the beveled recess of the gear 2,thus frictionally clutching the gear and driving it with the shaft, andthis gear being in mesh with the gear 7, fixed on the driven shaft 6,will impart motion to such shaft in one direction, the gear 3, which isalso in mesh with the gear 7, in the meantime moving idly on thedrive-shaft. Now if the lever be moved to the left it will release thegear 2 and cause the head 18 of the clutch member to frictionally engageand hold-the gear 3, driving the same with the shaft 1 and through itimparting motion to shaft 6 through the medium of fixed gear 7, thusdriving shaft 6 in the opposite direction.

It will be seen from this construction that I produce a reversingmechanism in which the direction of rotation of the driven shaft may beinstantly changed, and this by means of mechanism mounted upon a drive-shaft which stands at right angles thereto. It will IOO also be seenthatI produce an improved clutch member admirably adapted for thepurposes herein explained.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination with a clutch member comprising a body portion providedwith a peripheral groove, of friction-heads provided at opposite ends ofthe body portion, each head consisting of a lateral ange formed integralwith the body, a reduced core projecting from the flange parallel withthe body, friction material mounted on the core and a protectingdiskapplied to the end of the core over the friction material and secured tothe lateral ange by bolts or the like passing through the frictionalmaterial, aremovable split col- A EDWARD L. SHORE.
